The MC74AC574DWR2 is an octal D flip-flop featuring 3-state outputs, designed for high-speed and low-power applications. It includes a buffered common clock (CP) and a buffered common output enable (OE), allowing for efficient data storage on the LOW-to-HIGH clock transition. The device is functionally identical to the MC74AC374/74ACT374, with the primary difference being the pinouts. This flip-flop is suitable for use as an input or output port for microprocessors, with inputs and outputs positioned on opposite sides of the package for easier interfacing. The outputs can source or sink up to 24 mA, making it capable of handling bus-oriented applications. The MC74ACT574 variant offers TTL-compatible inputs, and both versions are available in Pb-free packages. The device operates within a supply voltage range of 2.0 to 6.0 V for AC and 4.5 to 5.5 V for ACT, with a recommended operating temperature range of -40¬8C to 85¬8C.
